"ro DA" comes out "For > every {DA}", which (I think) is equivalent to your original interpretation. I think we've had essentially this disagreement/misunderstanding before. In my book, "For any [given] x" means exactly the same as "For all/every x", but is easier to interpret correctly (as a universal quantification) in complex situations. > What you have here transcribes as "da de zo'u co'e da poi klama de". No, I disagree. That would be "For _some_ {DA}". > That leads to a tangent. One of my rules was in error.

I think this way lies madness. The first occurence must define the principal quantification, and subsequent quantifications select. > As you say, this is potentially recursive: > ro da poi broda de vau ro de poi brode de zo'u da brodi de ^ da? > meaning something like: > All X's which foogle a Y (every Y?) snorgle all Y's which > zarkify an X (every X?) > I nominate this sentence for Most Confused Sentence Of The Year.
